In an opening/closing body control device, catching determination part (15) determines whether or not a catching in an opening/closing body has occurred based on a value of current that flows in a motor; a plurality of sensors (51 to 53) disposed to be shifted by predetermined electrical angles detect positions of magnetic poles of the motor (40); a counterclockwise pattern storage unit (14) stores a counterclockwise pattern which is a pattern corresponding to outputs of the plurality of sensors (51 to 53) and a predetermined shift in the electrical angles; and drive command part (16) controls the drive circuit (30) using a clockwise pattern or the counterclockwise pattern based on the outputs of the plurality of sensors (51 to 53), and in a case where the catching determination part (15) determines that a catching has occurred, controlling the drive circuit (30) in a predetermined pattern for eliminating the catching.
